CONTROLLING-ENGLNE FOR PRESSES.

SPECIFICATION forming part of Letters Patent No. 637,571, dated November 21 1899.

' l AApplication filed September 8,1898. Serial No. 690,479. (No model.) V l To all whom, t may concern:

Beit known that I, EDWARD HETT, a citizen of the United States, and a resident of New York, (New Dorp,) in the county of Richmond, State of New York, have invented certain n ew and useful Improvements in Controlling-Engines for Presses, of which the following is a specification. i

My invention relates to presses, and more especially to devices for controlling the movements of parts of the mechanism in such presses-as, for example, for controlling the movements in a lithographie press of the printing-surfaces, the inking mechanisms, and the damping mechanism into and ont of operative position.

It has for its object to provide means for controlling the movements of parts of presses, especially movements of parts of the press into and out of operative position, to eect such control more easily, efiiciently, and with greater precision and certainty than has heretofore been possible, and preferably to do this automatically and without requiringachange in the direction of the motive power, and also to provide means by which the operator can readily put the automatic controlling mechanism into operation.

In the operation of the multicolor-press, in connection with which my improved devices are here shown and described, it is necessary to move the entire series of printing-surfaces out of or into contact with the impressionsurface, to move the inking mechanisms out of or into contact with the printing-surfaces by swinging the ink-frames carryingthe inking mechanisms, and to move the damping mechanisms out ofkor into contact with the printing-surfaces by swinging the dampingframes carrying the damping mechanisms, and it is in connection with these movements and to control them that my improved devices are herein shown and described.

In the preferred form of my improved controlling-engine shown and described herein I employ connecting mechanism or mechanisms between the driving mechanism of the controlling-engine, hereinafter referred to, and the part or parts of the press to be moved, connecting the said driving mechanism with the said part or parts of the press, driving mechanism, preferably driven -by the driving mechanism of the press, for imparting motion through the said connecting mechanism or mechanisms to the said part or parts of the press to be moved, and suitable clutch mechanism, preferably electric, and in part automaticallyo'perated to connect and disconnect the driving mechanism of the controlling-engine with some suitable source of power, preferabl y the drivin g mechanism ofthe press,and to connect the said driving mechanism of the controlling-engine with the said connecting mechanism or mechanisms and to disconnect them. I prefer to use in my controlling-engine driving mechanism which is capable of motion in either direction, as I am thus enabled by the use of the same controlling mechanism to impart to the part or parts of the press to be moved a movement one way or the other, as desired. Such movement one way or the other `I obtain by employing, preferably between the source of power and the driving mechanism of the controlling-engine, clutch mechanism which is capable of assuming anyof three separate positions, in one of which the source of power is wholly disconnected from the driving mechanism of the controlling-engine, in which case the part or parts of the press to be moved remain at rest, and in the other two of which 'posit-ions'the driving mechanism of the controlling-engine is connected with the source of power in one of said positions to impart motion in one direction to the driving mechanism of the controlling-engine to move the part or parts of the press one way and in the other` of said positions to impart motion in the opposite direction to the driving mechanism of the controlling-engine to move the said part or parts of the press the other way. My preferred form of mechanism for this purpose is shown in the drawings, and consists of two clutch gear-wheels intermediate between the source of power and the main shaft of my controlling-engine and a clutch automatically operated adapted to cause ono or the other or neither of the clutch gear-wheels to connect the source of power with the said shaft, although of course any other mechanism suitable for the purpose may be employed.

IOO

I will now proceed to describe the particular form of controlling-engine shown in the drawings herein.

Figure 1 is a side View of such controllingthe circuits :also-omitted. Fig. 7 is Vafro'nty engine and-of a part of a multicolor lithographic press with the casing and'with certain parts broken away to show more fully` the operation ofthe parts. Fig.-2 is a diagrammatic plan showing the circuits preferably used byl me in the operation of my 'controlling-A standard upon which it is mounted for oper-l ating the circuit-controllers hereinafterdescribed. Fig. 4 is a plan view ofv the same,vr

and Fig. 5 is a horizontal section of the same on the lines 5 5 of Fig. 3 viewed as shown by the arrow. Fig. 6 is a plan View of 'my im-v proved'controlling-engine with the driving mechanism for driving it omitted and with View, and Fig. 8 a side view, of thesame.` Fig.

9 is a vertical cross-section on the lines `9 9 of Fig. 6 viewed as shown by the arrow. Fig.

10 is a detail showing pawl 91 and'wheel .92;A

and their connections.

Y1 is the shaft upon which the impression-V' d ruxn 2 of the multicolor lithographie press (shown in part in Fig. 1) is located. lThis multicolor lithographie press is substantially the same as that shown and described in my said application Serial No. 593,796, and the mechanism of it will not be described in detail anyfurther than is necessary to convey a clear idea ofthe connection between it and my vimproved controlling-engine and the coneither direction and is preferably driven byv the driving mechanism of the press and. is connected by connecting mechanisms presently to be described with the printing-cylinders, damping-frames, and inking-frames. This shaft is shown in Fig. 2 as a single shaft 6, but I prefer to use for this purpose two shafts 6a 6b, as shown in Fig. 1. This shaft is provided with gear-wheels and with clutch mechanism, preferably electric.

It is immaterial whether one or'two shafts be used, as the eect is substantiallyl the same in both cases.

1, for the reason that the gear-Wheels can be y placed upon one part of this compound shaft and the electric clutch mechanisms on the other part, thus enabling a shorter shaft to be used and the controlling-engine to be made more compact and smaller in size. The shaft of the controlling-en gine is preferably driven Fig. 3 is a side view `wheel 1'1. l Ymounted on shaft 6b, as shown inl Fig. 1, and

`cordingly not shown.

I prefer the double form shown in Fig.

by. the dri-ving mechanism ofthe pre-ss, al-

; though any suitable driving mechanism may b'e employed for that purpose.

Y As shown in Fig. 1 ,the main driving-shaft 7 of the press carries atV one end a beveled gear-wheel 8, which meshes with Vgear-wheel 9 upon shaft 10.

vShaft l0 carries at its other end a beveled ,gear-wheel ll.

` In order` to impart motion to the shaft of the controling-engine in either direction, as

desired, two clutch gear-wheels 12 12 are interposed betweenthe shaft and beveled gear- Gearwheels 12 12 areeach loosely mesh with gear-wheel 11.I As shown, gearwheels 12-12 are each'rigidly lsecured to a sleeve 13, which turns loosely onshaft i6", and also carries atits other end gear-wheel 14, the latter meshing with gear-Wheel 15, lloosely mounted-on shaft 6a; 16 16va are'the two parts .of an electric clutch for connecting each gearwheell 15 with shaftv 6a, part 16a of the clutch being connected with shaft 6a so as tobe capa- A'bleof motion longitudinally' along the shaft,

but to rotate with the shaft. `This may be accomplished by any ywell-known 'meanssuch, for instance, vas'by spline and feather.

Part 16@ of each clutch is integral with its ygear-wheel land is loose upon shaft 6a. .The formv of thsclutch mechanism may be of any suitable kind and the details are ac- Eachl of the electric clutch mechanisms is so arranged that when lthe current is passed through it the two parts of the clutch mechanism will lock together, thus causingshaft 6a to rotate in one direction or the other, depending upon which one of the electric clutch mechanisms 16 16a is energized.

In this way the shaft aof thevcontrolling-engine is driven one way or the other, as desired. 17 is a gear-wheel loosely mounted upon vshaft 6a.

18 -18a are the two parts of an electric clutch mechanism for connecting gear-wheel 17 with shaft 6, partl 18V rotating with shaft 6a and movable longitudinally thereon and part 18 being integral with gear-Wheel 17. Gear- Wheel19, mounted upon sleeve 2O on shaft 6b, meshes with gear-wheel 17. Sleeve 20 also carries beveled gear-Wheel 21. When electric clutch mechanism 18 18a is energized, gear-Wheel 21 rotates one way or the other, dependent on the direction of rotation ofthe shaft 6a. Gear-wheel 21 is intermediate between the shaft of the controlling-engine and the connecting mechanism connecting the controlling-.engine with the -inking-frames. This connecting mechanism is as followsnamely, beveled gear-wheel 22 on shaft 23, beveled gear 24 on the other end of the shaft meshingwith beveled gear 25 on shaft 26, the

-latter carrying at its other end gear-wheel 27, gear-wheel 28 on shaft 29 meshing with gear 27 worm 30 on said shaft meshing with Worm-Wheel 31, mounted on shaft 1 of the shaft 33, carrying at its other end worm 3 5, which meshes with worm-wheel 36, secured to inking-frame 5. Each inking-frame has a similar worm-wheel 36,.shaft with worin 35, and beveled gear-wheel 33, meshing with the same teeth 32 on the worin-wheel y31. Thus whenever clutch mechanism 18 V18 is energized the shaft of the controlling-engine,

through gear-wheel 21 and the above-described connecting mechanism, moves all .of the inking-frames of the press simultaneously into or out of operative position, depending upon which one of the two electric clutch mechanisms 16 16lhL is energized. If one of the latter clutch mechanisms is energized, the inliing-fram'es are moved so as to throw the inking-rollers into operative position, and if the other clutch mechanism 16 16'a is energized the inking-frames are moved so as to move the hiking-rollers out of operative position.

Shaft 26 carries two gear-wheels 25 27, one on each side of the outer frame of the press, the inner gear 27 meshing with a beveled gear 28 on the shaft 29, having a worm 30 meshing with a similar worm-wheel 31, having similar teeth 32. Each inking-frame at one side of the press is similarly provided with a worm-wheel 36, worm on shaft 34, and beveled gear 33, meshing with teeth 32. The inking-frames at the other side of the press are connected with the inking-frames referred to above by any suitable means. Accordingly when electric clutch mechanism 18 18a is energized all the inking-frames on each side of the press are simultaneously swung so as to move the inking-rollers into or out of operative position, depending upon which one of the two electric clutch mechanisms 16 16 is energized.

The mechanism for moving the dampingframes, so as to move the dam ping-rollers into or out of operative position, consists of the following:

37 is a gear-wheel loosely mounted upon 6U.

38 and 38"L are the two parts of an electric clutch mechanism for operatively connecting gear-wheel 37 to shaft 6a, 38 revolving with `the shaft and having longitudinal motion thereon, as by spline and feather, and 38n being fixedly secured by sleeve 39 to gearwheel 37.

40 is a gear-wheel mounted upon sleeve 41,v

the latter loosely mounted upon shaft 6b and also carrying beveled gear-wheel 42. When electric clutch mechanism 38 38a is energized, gear-wheel 42 is rotated one way or the other, depending upon the direction of rotation of shaft 6a in the manner above described. The connecting mechanism between gear-wheel 42 and the damping-frames of the press consists of the following-described mechanism: beveled gear-wheel 43 on shaft 44, beveled gear-wheel 45 on the other end of the shaft, beveled gear 46 on shaft 47, meshing with beveled gear 45, worm 48 upon shaft 47, meshing with worm-wheel 49 upon shaft 50. Shaft 50 4frame 4.

runs across to the other sideof the press and through the frame. It carries at its farther end a beveled gear-wheel, (not shown in the drawings,) the latterbeveled gear-wheel meshing with beveled gear 51 on shaft 52, worm 53 at the farther endof shaft 52 meshing with worm-wheel 54'on shaft55, eccentric 56, fixedly mounted on shaft 55 and working i`n a similarly-shaped opening in wheel 57, loosely Vmounted on shaft 1, arms 58, each with ngersencircling the pin 59, secured to wheel 57, and each pivoted at and having arms 61 62, the latter being connected to damping- On the nearer side of the machine there are also similar parts corresponding to beveled gear on shaft 50, referred to above and not shown, beveled gear 51, shaft 52, worm 53, gear-wheel 54, shaft 55, eccentric 56, Wheel 57, arms 58, and the other connections described above between it and the dampingframes, so that each set of damping-frames is slightly rocked-one way 01 the other whenever electric clutch mechanism 38 3 8a is energized. Each set of damping-frames has corresponding arms 58, pins 59, and crank-arms 61 62, so that all of the damping-frames of the press are simultaneously rocked backward or forward, so as to move the damping-rollers into or ont of operative position, depending upon which one or the other of electric clutch mechanisms 16 16a is energized.

The mechanism for controlling the movement of the'printing-cylinders into or out of operative position consists of the following:

63 is a gear-wheel loosely mounted upon shaft 61.

64 and 64ZL form electric clutch mechanism for operatively connecting gear-wheel 63 with shaft 6, 64 rotating with said shaft and being capable of longitudinal motion thereon, as above described, and 64 being integral with gear-wheel 63.

65 is a gear-wheel loosely mounted upon shaft 6b. As electric clutch mechanism 64 64 is energized gear-wheel 65 is caused to rotate one way or the other with shaft 6a, depending upon which one of the two electric clutch mechanisms 16 16n is energized. The connecting mechanism between gear -wheel 65 and the printing-cylinders consists of the following mechanism: gear-wheel 66 on shaft 67, the latter carrying at its other end worm 68, worm-wheel 69, meshing with worm 68and mounted on shaft 70, the latter carrying two gear-wheels 71, one on each side of the press, one only of which is shown in the drawings, each gear-wheel 71 meshing with a toothed segment 72 of a wheel `73,loosely mounted upon shaft 1 of the press. Each wheel 7 3 on each side of the machine carries pins 74, working in a slot 75 on the two inner ends of the toggle-joint 76 76, the inner end of the togglejoint toward the center of the press being free to 4move radially inward or outward from the center, theoutward end of the toggle-joint being secured to the framework at 77. To the inner end 78 of each toggle-joint is secured a IOO IOS

IIO

shaft 79, carrying'at its outerv end one of thel cordingly as wheels 73 oscillate one way or' l the 'other when electric mechanism 64 64:'UL is energized and one or the other of electric clutch mechanisms 16 16a is energized the printingcylinders 3 3 are moved inward against the drum, so as to be in operative po` .sition for printing or are moved outward Vss therefrom. By means of thetwo clutch gearwheels 12 12 and their respective clutch mechanisms 16 16a intermediate between the shaft ofthe controllingengine and the driving mechanism of the press I am enabled to rotate the shaftof the controlling-engine in one direction or the other, as desired, by energizing one or the other of the said electric clutch mechanisms, and by means vof each gear-wheel and its respective electric clutch mechanism intermediate between the shaft of the controlling-engine and the connecting mechanism connecting with ya different part of the press to be moved, as above described, I am enabled to impart motion to the different parts of the press to be moved in one direction or the other, depending upon the di rection of rotation of the said shaft of the controlling-engine, or I am enabled to stop the motion of any of said part or'parts by deenergizingthe proper electrical clutch mechanism.

The mechanism of my controlling-engine may be itself controlled by the operator in any suitable manner and by any suitable means. I prefer, however, to effect such conv trol by means of electric circuits which are y put into operation by circuit-controllers under the controlof the operator, but whosel gized. I also employ a series of circuits each' containing an electromagnet for the purpose of making and breaking the clutch-circuits, and these circuits are denominated herein and will be referred to as operating-circuits. Each clutch-circuit has its corresponding operating-circuit. Each operatingcircuit is preferably normally open and has a circuitcontroller which can be closed by the operator. Each operating-circuit is thu-s partially Acuits is but momentary, I employ a catch for seizing and holding the circuit-controller of the different clutch-circuits in their closed or operative position, thus keeping the clutchcircuits through the clutch .mechanism closed until it becomes necessary to open them. They are automatically opened by the'operation of my controlling-engine in the manner presently to be described. For the purpose 0f opening the clutch-circuits, Ihave arranged la series of circuits, which I will designate and refer to herein as releasing-circuits, each containing an electromagnet adapted when operated to withdraw the catch, holding one of the circuit-controllers of the clutch-circuits closed, so as 'to release the said circuit-controller and permitting the clutchcircuit to open and denergze the clutch mechanism. For the above purpose I preferably place a circuit-controller in each releasing-circuit,

which is adapted to be closed automatically by the operation of the controlling-engine or a part of the press to close the releasing-circuit and to energize an electromagnet therein to withdraw the catch ofthe clutch-circuit for 'the above purpose, as will be presently described.

In Fig. 2 I have shown a diagrammatic plan of the various circuits referred to above and their connections. In this gureI haveshown the shaft 6 of the controlling-engine as being composed of but one part and as carrying gear-wheels 12, 2l, 42, and 65, (here shown as spur gear-wheels,) connecting with the various trains of gearing comprising the connecting mechanisms connecting with the diiferent parts of the press to be moved and as also carrying clutch mechanisms 16 16a, 18 18a, 38 38, and 6ft 64a as arranged upon one shaft 6. This construction, as above stated, is, however, in'all substantial respects the same as that shown in Fig. 1, where the shaft of the `controlling-engine consists of two separate shafts 6a 6b. In Fig. 2` Ihave not shown the driving mechanism of the press nor have I shown the connecting mechanisms connecting the different gear-Wheels with the dierent parts of the press to be moved.

In the operation of my improved, controlling-engine, as shown in the drawings, the operator turns a hand-wheel toacertain predetermined point, thereby operating a circuitcontroller to close the operating-circuit,which controls and thereby closes a circuit-controller in the clutch-circuit of one of the clutch mechanisms 16 16, thus causing the shaft of the IOO esatti. a

controlling-engine to be driven by the driving mechanism of the press in one direction. By the same movement of the hand-Wheel the operator also operates another circuit-controller, Which closes an operating-circuit, and thereby closes circuit-controllers in each of the clutch-circuits through clutch mechanisms 18 18a 38 38LL 64 64a, thus operativelyconnecting gear-Wheels 2l, 42, and 65 With the shaft of the controlling-engine, and thereby irnparting motion through the various connecting'mechanisms to the damping-frames, inking-frames, and printing-cylinders of the press, causing them to move into their operative or printing positions. The circuit-controllers of the operating-circuits, thus closed by the operator by turning his hand-Wheel, together with other circuit-controllers for the releasing-circuits, presently to be described, are preferably placed upon another shaft 8l, which is driven by the main shaft of the controlling-engine. For purposes of clearness and brevity I Will hereinafter speak of this shaft as a circuit-controller shaft. After the controlling-engine has thus been started by the operator the circuit-controller shaft continues to rotate until it automatically closes a releasing-circuit, which opens the circuit-controller of the clutch-circuit through the clutch mechanism 16 16, which has heretofore been energized, as above described, thus disconnecting the shaft of the controlling-engine from the driving mechanism. The controlling-engine therefore at once comes to rest, causing the printing-cylinders, damping-frames, and inking-frames also to stop immediately. This action is timed so as to occur exactly at the time that the printingcylinders, dam ping-rollers, and inking-rollers are in their operative position ready for printing. To insure the stoppage of each of these dierent parts at the proper time, I also, preferably, provide means fordisconnecting the respective gear-Wheels 21,42, and 65 from the shaft of the controlling-engine, which means are automatically actuated by the dampingframes, inking-frames, and printing-cylinders when they respectively reach the limits of their movements, in a manner presently to be described. The press is new in readiness for printing.

When the operator desires to discontinue the printing operation, he moves the handwheel again to another predetermined point, Which o'perates certain circuitcontrollers to close operating-circuits and inthe manner above described to close the clutch-circuits through the other clutch mechanism 16 16a and through clutch mechanisms 18 18, 38 38, and 64- 61, This causes the shaft of the controlling-engine to rotate in the opposite direction and through the various connecting mechanisms to move the printing-cylinders, damping-frames, and inking-frames in the opposite direction, moving them out of operative or printing position. The circuit-controller shaft, however, continues to rotate,

being driven in the manner presently to be described by the main shaft of the controlling-engine until it automatically operates the circuit-controller in another releasingcircuit, Which opens the circuit-controller in the clutch-circuit through the clutch mechanism 16 16, last referred to, thus causing the shaft of the controlling-engine to stop, and thereby stopping the movements of the printing-cylinders, damping-frames, and inkingframes. To insure the stoppage of each of these parts at the proper point, I also provide means automatically actuated by each of these parts at the limit of its movement for disconnecting the gear-wheels 21, 42, 'and 65 from the shaft of the controlling-engine.

The mechanism and circuits :for accomplishing the above results I Will now proceed to describe. The circuit-controller shaft referred to above is omitted from Fig. 1, but is shown in Figs. 2, 6, and 7, and is represented by 8l. This shaft is driven by the main shaft of the controlling-engine by means of the following mechanism: Sleeve 20, with gear-Wheel 19 and beveled gear 21, is fast upon shaft 6b, so that when electric clutch mechanism 18 18a is energized shaft 6b rotates with shaft 6a. This rotation of 6b is sometimes in one direction and sometimes in another, dependent upon which one of the two clutch mechanisms 16 16 is energized. Shaft 81 is driven from shaft 6b, but as itis important that shaft 81 shall always rotate in the same direction I communicate motion from shaft 6b to shaft 8l by the following-described mechanism, Which changes the varying motion of shaft 6b into a rotation of shaft 81 in one direction only, and which also permits shaft 81 to be rotated independently of shaft 6", for a purpose presently to be described. Looscly mounted upon shaft 6b are two beveled gear-Wheels 82 82, facing each other, and each having a collar 83, provided With ratchetteeth, .the teeth of the collar of one gear- Wheel pointing in an opposite direction to those of the collar of the other gear-Wheel. Upon shaft 6b, between the gear-Wheels, are two collars 85 85, each provided with ratchetteeth facing the ratchet-teeth of collar 83 of one of the gear-Wheels. The collars 85 are splined upon shaft 6b and are connected to it by any suitable means, as by spline and feather, so as to rotate With it and to be free to slide longitudinally a short distance thereon.. These collars 85 are held toward the ends of the sleeve by coiled spring 86. As shaft 6h rotates in one direction the teeth of one of the collars 85 engage with the ratchet-teeth of one of the collars of the gear- Wheels and rotate that wheel, While the teeth of the other collar 85 slip over the teeth of the collar of the other gear-Wheel. As the shaft rotates in the other direction the latter gear-Wheel is rotated, While the former remains loose upon the shaft. 87 is a shaft, which will hereinafter be spoken of as 'the connecting-shaft, having at one end a bev- IOO IIO

eled gear-wheel 88,`meshing with gear-wheelsV by shaft 6b, connecting shaft 87., is drivenv always in the same direction, and through. worm 89,wormwheel 90, pawl 91, and ratchetwheel 92 it drives shaft 81 always in the same direction. This arrangement also permits circuit-controller shaft 81 to be turned independently of shaft 6b in a manner presently to be described. The circuit-controllers referred to above, which control the operatingcircuits and part of the releasing-circuits, are mountedupon shaft 81. They consist of the wheels 94, 95, 96, and 97, all mounted upon androtating with shaft 81. Each of these circuit-controller wheels has'two rings, one, 98, composed of metal or'other suitable conducting material throughout its entire ,cir' cumference, the other, 99, consisting chiey` of insulating material, provided on its surface lat one orfmore points with metallic or conducting portions 100. A metallic or conducting bridge 101 connects metallic portion 100 with `ring 98. Contact-points 102 102, connected with wires, press against the two rings 98 and 99. When one of these contact-points g 102 presses against metallic part 100 of ring its lower end a beveled gear-wheel 106.

clearly shown in Figs. 3, 4, and 5.)

99, a circuit isclosed through contact-points 102, ring 98, bridge 101, and metallic part 100 of ring 99; but when one of the contact-points 102 presses against the non-conducting partsk of ring 99 the circuit is broken. In Figs. 2f, 2b, 2,.and 2c1 I have shown the wheels 94, 95, 96, and 97 in the form of adiagram the more clearly to show the 'electrical connection of the parts, ring 98 being represented by the light inner ring andV ring 99 by the outer dark ring, the non-conducting portions of the latter ring being represented in black and the conducting portions 100 of the said ring 99 and bridge 101 being represented as white. The size and arrangement of the metallic conducting portions 100 Vary somewhat among dierent rings 99, as shown in Figs. 2, 2b, 2C, and 2d, for a purpose presently to be described.

The various circuits employed byme and the means for operating them will now be described in the order in which they are brought into play in the operation of the machine.

The operator starts the operation of the inachine by means of a hand-wheel 103. (Most This hand-wheel is mounted on a shaft 104, turning loosely in standard 105 and carrying at The latter meshes with beveled gear-wheel 107 on shaft 108, the latter also carrying beveled gear-wheel 1.09 at its other end. Gear-wheel 109 meshes with beveled gear-wheel 110 on `circuit-controller shaft 81. Thus by turning lreaches the point marked On.

the hand-wheel shaft'81 can berotatedf Oft Fastened to shaft 104 immediately `overl plate 111 is an indicator-linger 112.

When the machine is at rest, the indicatorfinger rests opposite to -the word Stop .(Shown in Fig. 4.) When the operator desires to put the press into operation, he turns the lhand-wheel in the direction indicated by the arrows in Figs. 4 and 5 until indicator 112 This turns Stop On, Print, andshaft 81 and -with it wheels 94, 95, 96, and. 97 y in the direction indicated by the arrow in Fig. 2a until the conducting portions 100 of wheels 96 and 94 are under one of the contact-points 102. This closes an operatingcircuit, which controls and closes the clutchcircuit through the clutch mechanism 16 16"L to the left, as shown in Fig. 2, which, for the purpose of identification, I have in that ligure also marked with the letter A to distinguish it from the other clutch mechanism 16 16a to, the right, which I have in-said figure designated by the letter B, thus connecting the main shaft of the control1ing-engine with the driving mechanism ot' the press and rotating that shaft in one direction. It also closes an operating-circuit, which closes the circuit-controllers in the three clutch-circuits through clutch mechanisms 18 18a, 38 38a, and 64 64a, thus connecting the shaft of the controlling-engine with gear-wheels 21,

42, and 65 and moving the inking-frames, damping-frames, and inking-cylinders of the press. These circuits are as follows: The

:operating-circuit closed by circuit-controller 96 consists of negative pole, switch 113, mainline wire 114, wire 115 116, contact-points, rings, and bridge of wheel 96, wire 117, electromagnet 118, wire 1192M 120, main-line wire 121, to positive source of electrical supply. This energizes magnet 118 and closes circuitcontroller 119 of the clutch-circuit through `clutch mechanism 16 16a, (A.) This latter cl utch-circuit'consists of negative pole, mainline wire 114, wire 122, contact-point 123,

. bridge 124 of circuit-controller 119, contact- Ipoint 125, wire 126, electric clutch mechanism 16 16a, (A,) wire 127, contact-point 128,

bridge 129 on circuit-controller 119, contactpoint 130, wire 120, main-line Wire 121 to positive pole. The closing of this circuit energizes electric clutch mechanism 16 168L (A) and operatively connects the shaft of the controlling-engine with the driving mechanism of the press and rotates that shaft in one direction. As the conducting-surface 100 of circuit-controller Wheel 96 is short, the clos*- ing of ythe circuit/through magnet 118 is but momentary. In order, therefore, to prevent the circuit through electric clutch mechanism 1'6 16a (A) from being broken too soon, I employ a-catch 131,v which is spring-pressed, the spring not being shown, however, adapted IOO IIO

to seize and hold circuit-controller 119 when attracted'by magnet 118.v For this purpose 1 provide a toe 132 on catch 131, which falls behind and locks circuit-controller 119 in its closed position until released, as hereinafter described. When the conducting portion 100 of circuit-controller wheel 94 comes into contact with contact-point 102, it closes the following operating-circuit: main-line wire 114, wire 133, magnet 134, wirc135, magnet 136, wire 137, contact-points, rings, and bridge of circuit-controller wheel 94, Wire 138, magnet 139, wire 140, and main-line Wire 121. This operating-circuit energizes magnets 134, 136, andV 139. Magnet 134, in the same manner as above described with reference to magnet 118, closes circuit-controller 141, which closes the clutch-circuit through electric clutch mechanism 18 18. This circuit is as follows: main-line Wire 114, Wire 142, contact-points and bridge of circuit-controller 141, Wire 143, electric clutch mechanism 18 18a, Wire 144, the other contact-points and bridge of circuit-controller 141, wire 145, and main-line wire 121. Electromagnet- 136 similarly closes circuit-controller 146, closing the clutch-circuit through electric clutch mechanism 38 38a.

This clutch-circuit consists of main-line wire 114, wire 147, contact-points and bridge of circuit-controller 146,Wire 148, electric clutch mechanism 38 38a, wire 149, the other contact-points and bridge of circuit-controller 146, wire 150, to main-line Wire 121. Electromagnet 139 similarly closes circuit-controller 151, which closes a clutch-circuit through clutch mechanism 64 64a. This clutch-circuit consists of main-line wire 114, contactpoints and bridge of circuit-controller 151, wire 152, clutch mechanism 64 64a, wire 153, the other contact-points and bridge of circuit-controller 151, and main-line Wire 121. By moving the hand-Wheel until the indicator reaches the point marked On 7)the operator has thus connected the main shaft of the controlling-engine with the driving mechanism of the press, thus rotating that shaft in one direction, and has also by the same operation energized electric clutch mechanisms 18 18a, 38 38, and 64 64, connecting the shaft of the controlling-engine with gear-Wheels 21, 42, and 65, and through the various connecting mechanisms imparting motion to the inkingframes, damping-frames, and inking-cylinders of the press. At the same time the rotation of the shaft of the controlling-engine, through connecting-shaft 87, as above described, imparts rotation to shaft 81. The latter shaft, therefore, continues to rotate, and as it does so, through the gearing connecting hand-Wheel 103 With shaft 81, the hand-wheel is also rotated. is automatic. By the time the indicator-finger 112 has arrived opposite the point on the plate 111 marked Print circuit-controller Wheel 95 has rotated half-way until o`ne of the conducting portions 100 of its ring 99 makes contact with contact-point 102. This This operation" the shaft of the controlling-engine from the y driving mechanism and causing that shaft to immediately stop, thus stopping the movement of the dierent parts of the press. The said releasing-circuit is as follows: main-line wire 114, wire 122, Wire 154, magnet 155, wire y156, Wire 157, contact-points, bridge, and conducting portion of circuit-controllerWheel 95, wire 158, wire 159, end of wire 127, contactpoints and bridge of circuit-controller 119, wire 120,-and main-line Wire 121. Thus as magnet 155 is energized it attracts its armaturelever,catch 131,Withdraws the catch from circuit-controller 119, and permits that circuit-controller to open and break the circuit through electric clutch mechanism 16 16,(A.) The operation of the controlling-engine has thus been automatically stopped by the controlling-engine itself. In order to insure that each of the different parts of the press that are being moved-to Wit, the printing-cylinders, damping frames, and inking-framesshall stop at exactly the right spot, 1 also preferably provide means by which each of those parts automatically denergizes electric clutch mechanisms 64 64a, 38 38, and 18 18, thus insuring the stoppage of these different parts of the press at a predetermined point, preventing breakage of the parts, and insuring certainty and precision of movement. The mechanism for this purpose will be presently described. The parts of the press-namely, the printing-cylinders, damping-frames, and inking-frames-are now in their operative position ready for printing and .the printing proceeds in the usual manner.

When the operator desires to discontinue the printing, he moves hand-wheel 103 so that the indicator-point moves from the point marked Print, where it had stopped, until it reaches the point marked Off. This movement of the hand-Wheel moves circuit-controller shaft 81 until the conducting portion 100 of circuit-controller wheel 97 comes under one of the contact-poin ts 102. In the manner above described this closes an operatingcircuit, which closes a clutch-circuit through the other clutch mechanism 16 16a (B) and operatively connects the main shaft of the controlling-engine with the driving mechanism of the press in such a Way that the shaft rotates in the opposite direction from that of its former rotation, and at the same time the other conducting-surface 100 on circuit-controller wheel 94 also comes into contact with one of the contact-points 102, closing the operating-circuit above' described through magnets 134, 136, and 139, closing circuit-controllers 141, 146, and 151 of the clutch-circuits through clutch mechanisms 18 18, 38 38a, and 64 64a in the manner above described, thus connecting the shaft of the controllingengine with gear-Wheels 21, 42, and 65 and IOO IIO

As the standard 72 and wheels 73 reciprocate contact-points 175 176 make contact jat the limit of their movement in one direction, thus closing the said releasing-circuit through electromagnet 17 2, withdrawing the catch, breaking the clutch-circuit, and stopping the printing-cylinders in their movement.

which oscillates wheel 57, which wheel imparts a reciprocating movement to the various damping-frames of the press, as above described.

uniting into wire 2.04, end of wire 144, con- Y 141, and permitting circuit-controller 141 to open andbreak the circuit through electric clutch mechanism 18 18a. This disconnects gear-wheel 21 from the shaft of the controllingengine and immediately stops the movement of the inking-frames. The operation of the said releasing-circuits is thus automatic and needs no supervision on the part of the operator, is simple in its operation and certain in its action, eiectually prevents breakage of the parts of the press, while at the same time stopping the printing cylinders, dampingframes, and inking-frames at a predetermined point with certainty and precision, and releasing the various catches preparatory to the next operation of the controlling engine. While the operator by closing the releasingcircuits through releasing-magnets 155 and 170 can disconnect the shaft of the controlling engine from the driving mechanism which is imparting motion to it and'can thus at will stop the movements of the different parts of the press, the above automatic means guards against any negligence on the part of the operato and insures the stoppage of each different part of the press being moved eX- actly at a predetermined point. It is evident of course thatin place of the electric circuits employed in this automatic releasing mechanism mechanical means automatically actuated bythe different parts of the press to be moved could be substituted in place thereof without departing from my invention. I prefer, however, the arrangement herein shown and described for this purpose.

In order to insure that the different catches will seize and hold their respective circuitcontrollers, I preferably insertin the conducting portion 100 of circuit-controllers 94, 96, and 97 a piece of insulation 205. (Shown in black in Figs. 2, 2C, and 2d.) The insertion of such an insulating-piece within conducting portion 100 causes a second sudden pull to be exertedby each electromagnet on its circuitcontroller, thus tending to insure that the catch will seize and hold the circuit-controller. When any of the parts of the press are to be first started and circuit-controller 151,

146, or 141 is closed, the circuit through its corresponding releasing-magnet is of course closed at the same time through cont-actpoints 175 and 1.76, or 186 and 187, or 199and 200, thus tending to catch 151rt or 146 or 141 from seizing and holding its circuit-controller closed. To overcome this difliculty,I make the conducting-surfaces on the circuit-controlling wheels of sufficient length to insure the starting of the various parts of the press and the consequent sepa-ration of the contactpoints above referred to before the breaking of the operating-circuits, this insuring the proper operation of the catches. 206 (shown in Fig. 6) is a switch-box for holding circuitcontroller 151 and its contact-points and catch and electromagnets 139`and 172. 207, 208, 209, and 210 are similar switch-boxes,holding, respectively, circuit-controllers 119, 164, 146, and 141 and their respective catches, contact-points, electromagnets, and connections. These switch-boxes may be made in any suitable manner, although Iprefer the form which is shown and described-in my said application for a patent tiled herewith and designated as Case A. As the form of these boxes' forms no part of my present invention, I have not shown or described them in detail.

In the form of controlling-engine shown in the drawings the driving mechanism of the controlling-engine consists of the shafts 6 or 6n 6b and theirconnections. The sourceofpower for the controlling-engine is the driving mechanism of the press acting through shaft 10 and its connections. The connecting mechanism between the driving mechanism of l[he controlling-engine and the damping-frames consists of the train of gearing comprising gears 42 43, shaft 44, and the other gearing connecting said shaft 44 with the dampingframes. The connecting mechanism between the driving mechanism of the controlling-engine and the inking-frames consists of the train of gearing comprising gears 21 22, shaft 23,and the other gearing connecting said shaft 23 with the inkframes. The connecting mechanism between the driving mechanism of the controlling-engine and the printing-surfaces consists ofthe train of gearing comprising gear-wheels 65 66, shaft 67, and the other gearing connecting said shaft with the printing-surfaces. The clutch mechanism to connect the source of power, the driving mech'- anism of the press, with the driving mechanism of the controlling-engine consists of the two clutch gear-wheels l2 and 12 and electric clutches 16 16 (A) and 16 16"l (B). The clutch mechanism to connect the driving mechanism of the controlling-engine with the connecting mechanism leading to the dampingframes consists of the gear-wheel 42 and electric clutch 3S 3&2 Similarly the clutch mechanism to connect the driving mechanism of the controlling-engine with the connecting mechanism leadingto the inkingmechanisms consists of gear-wheel 2l and electric clutch 1S 18, and the clutch mechanism to connect the said driving mechanism with the connecting mechanism leading to the printing-surfaces consists of gear-wheel 65 and electric clutch 64 64.

In the drawin in this case my controllingengine has been shown as controlling the TOO IIO

movements of the printing, inking, and damp- .intervening between the driving mechanism ofthe controlling-engine and the different parts of the press are shown as consisting of trains' of gearing. Such connecting mechanisms may, however, consist of any other form of mechanism suit-able for the purpose. Likewise the means for operating the clu tchmechanisms may be varied from those shown in the drawings. "y

My improved devices are simple in character, compact in form, and are easily operated.

By means of them the movements'of different parts of the press are easily, automatically,

and quickly controlled, and the operator is enabled to move such yparts automatically to any desired position with certainty and precision and to time such movements with exactness without any supervision other than is required to turn the hand-wheel to start the operation. Moreover, by my improved means the operator is enabled with great ease to put the automatic controlling mechanism into operation.

This application is designated as Case y C to distinguish it from two other applications for controlling-engines filed by me simultaneously herewith and designated as Case A and Case B.
